Famco Chimney Cap & Crown in San Francisco: What to Know First
As an independent Famco service provider, we install, repair, and replace Famco chimney caps and crowns throughout San Francisco, with most jobs completed in a single visit and upfront pricing before any work begins. A standard Famco cap replacement or crown repair typically runs $280-$650 depending on the series and access, and we carry common Famco hardware so you’re not waiting on parts. This page is for homeowners who already have a Famco cap or crown on their chimney and want it fixed by technicians who know the difference between a 300-series stainless cap and a galvanized economy line without climbing down to check a manual. If that sounds like your situation, call us at (855) 408-5567. A live person answers, 24 hours a day.
How Famco Products Fail - and How We Fix Them
- 300-Series stainless caps with cross-break lid fatigue. The stamped lid on older 300-series units develops stress cracks right at the cross-break seam, especially on west-facing chimneys in the Sunset and Richmond where salt-laden fog cycles through daily thermal expansion. We replace with a heavier-gauge Famco-compatible lid or step up to a Gelco equivalent when the flue configuration allows.
- Galvanized economy caps (GEC line) with base rail rust-through. These were common on contractor-grade installs in the 1990s and early 2000s, particularly in Bayview and Visitacion Valley. The galvanized coating fails at the base rail first because that’s where condensation pools. We don’t patch these. We pull the cap, assess the crown beneath, and install a stainless replacement that outlasts the house.
- Multi-flue caps with improper overhang causing crown erosion. Famco’s multi-flue units require precise overhang calculations. When a previous installer eyeballed it, San Francisco’s driving winter rain gets behind the cap and erodes the crown in three to five years. We measure flue spacing, calculate proper drip edge, and reset or rebuild the crown before the cap goes back on.
- Crown-mounted caps with stripped tapcon anchors. The original masonry anchors on 2000s-era Famco crown mounts loosen in San Francisco’s soft, sand-heavy mortar, especially on pre-1940s chimneys in Noe Valley and the Mission. We drill deeper, use expansion anchors rated for the load, and bed the mounting flange in polyurethane sealant so it doesn’t work loose.
- Custom copper caps with solder joint failure at the finial. Famco’s custom copper line is beautiful, but the soldered finial joint is a known weak point where the Pacific’s thermal cycling eventually opens a pinhole leak. We resolder with 95/5 tin-silver, which handles expansion better than the original 50/50, and we document the repair with photos for your records.
Our Famco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, asks about your cap or crown symptoms, and books a window. We ask if you know the Famco series number or can text a photo of the existing unit.
- 2
Level-2 camera inspection and roof assessment. Our technician arrives in uniform, runs a camera up the flue to check for damage beneath the cap, and photographs the crown from the roof. You see the photos. We give you a plain-English verdict.
- 3
Parts decision. If your Famco series is still in production, we quote OEM. If it’s discontinued, we specify a quality aftermarket equivalent from Gelco or Olympia Chimney and explain the trade-off in gauge, finish, and warranty terms. No surprises on the bill.
- 4
Repair or replacement. We complete most Famco cap and crown jobs in one visit. Crown repairs get a slurry mix rated for San Francisco’s freeze-thaw cycles. Crown coatings get two passes with proper cure time between.
- 5
Post-job test and documentation. We run water over the cap to verify drainage, check that the flue draws correctly, and email you photos of the finished work with your invoice. The 90-Day Done Right Promise goes into effect automatically. In writing, no arguing.
- 6
Cleanup and walkthrough. We haul away the old cap, sweep the roof and yard, and walk you through what was done. If the flue isn’t right, the fire isn’t right. Everything else follows from that.

Why San Francisco Homeowners Call Hearthstone Chimney Co. of San Francisco for Famco Work
We’ve been on San Francisco roofs since 1984. Warren Eckhart learned this trade in the Outer Sunset, climbing Victorian chimneys while the fog was still burning off, and he built this company on the principle that a sweep who rushes the inspection will rush the repair. Our technicians are background-checked, uniformed, and trained on Famco’s product lines alongside DuraFlex, HeatShield, Gelco, and Olympia Chimney systems. If your Famco part is obsolete, we have alternatives in stock. The 90-Day Done Right Promise covers every job in writing. Calls are answered by a live person, 24 hours a day, 7 days a week. Most Famco cap and crown jobs finish in a single visit. That’s the square deal: no surprises on the bill, and we’ll be there when we say.
FAQs
The original Famco warranty on most residential caps expires after one year from manufacture, so typical San Francisco homes with caps installed five to fifteen years ago are already outside that window. For newer units, using an independent service provider like us does not void a valid warranty provided the repair follows Famco specifications. We document our work with photos in case you ever need to file a claim. Call (855) 408-5567 if you want us to verify your cap’s manufacture date.
We maintain stock of common Famco hardware, but some series from the 1990s and early 2000s are fully discontinued with no OEM support. When that happens, we source dimensionally compatible replacements from Gelco or Olympia Chimney, match the gauge and mesh specification, and install with the same mounting geometry. We explain the substitution before any work begins. For a free assessment of your specific cap, call (855) 408-5567.
Crown coating costs less upfront, typically $320-$480 versus $380-$580 for partial rebuild, but coating only works when the underlying concrete is structurally sound with surface spalling less than a quarter-inch deep. If the crown has through-cracks, exposed rebar, or more than forty percent surface loss, coating traps moisture and accelerates decay. We give you an honest verdict after inspection, not a sales pitch. Call (855) 408-5567 for a free evaluation.
Most Famco cap replacements are completed same-day or next-day because we carry standard sizes in our warehouse. Custom sizes or multi-flue units may need one to two business days for fabrication. Emergency calls, like a cap that has blown off in a winter storm, get priority scheduling. A live person answers the phone 24 hours a day at (855) 408-5567 to book your slot.
Yes. We work exclusively with professional-grade brands including DuraFlex liners, HeatShield resurfacing systems, Gelco caps, Olympia Chimney components, and Copperfield supplies. If your chimney has mixed brands or you’re considering upgrading from a Famco galvanized line to a Gelco stainless unit, we specify the right fit for your flue and roofline. Call (855) 408-5567 to discuss your setup.
